Answer:
10 pounds.
Step-by-step explanation:
Let x pounds be the amount of mixed nuts we require.
Amount of peanuts in this mix = 0.70x pounds. Amount of peanuts in the 20% mix = 0.20*15 = 3 pounds.
So we have the equation:-
0.70 x + 3 = 0.40(x + 15)
0.70 x + 3 = 0.40(x + 15)
0.70x + 3 = 0.40x + 6
0.70x - 0.40x = 6 - 3
0.30x = 3
x = 10.

Answer:
y=250x+2000
Step-by-step explanation:
The farmer starts with 2000 trees and adds 250 each year.
Year 0 2000
Year 1 2000 + 250 = 2000+ 1(250)
Year 2 2000 + 250 +250 = 2000 + 2(250)
Year 3 2000 + 250 + 250 + 250 = 2000 + 3(250)
Year 4 2000 + 250 + 250 + 250 + 250 = 2000 + 4 (250)
.....
Year X 2000 + 250x
Answer:
Her daughters age: 1/2x
Step-by-step explanation:
Let's say Rani's present age is x. Her age is twice the age of her daughter.
So if Rani's age is 20, her daughters age would be 10, because Rani is twice the age of 10; so 10 times 2 would be 20.
1/2(20)=daughter's age
so if you substitute x into 20 because we don't actually know Rani's age, it would be 1/2(x)=daughter's age.
hope this helped :-) <3
